Wired vs wireless security cameras

(Why should I even Care)

When you compare wired vs wireless security cameras, the biggest difference is how they get power and video.

Wired cameras send power and video through one cable to a recorder, so they record all day and night without relying on WiFi or batteries. Wireless cameras send video over WiFi, and some run on batteries. That makes them quicker to put up, but less reliable when it matters.

Here is what actually changes between the three types, and why we recommend wired cameras for your home's main security. This guide to wired vs wireless security cameras covers power, signal and recording.

What is a wired security camera?

Most wired systems use one network cable per camera. That single cable carries both power and video back to a recorder, called an NVR. This is known as PoE, which stands for power over ethernet.

Because nothing travels over WiFi, the video does not drop out when the signal is weak. And because the camera is always powered, it can record all day and night, every day.

What is a WiFi camera?

A WiFi camera sends its video over your home network. It is often sold as wireless, but it still needs power, usually from a nearby power point or a power cable run to the camera.

How well it works depends on your WiFi. Brick walls, distance from the modem and a busy network can all cause dropouts, and a dropout can mean a gap in your footage.

What is a battery camera?

Battery cameras are the easiest to put up, because there are no cables at all. The trade off is power. To make the battery last, most only wake up and record when they detect movement, and the battery needs recharging or replacing.

That means they can miss the moments just before something triggers them. There is no continuous footage to look back through, and if the battery runs flat, the camera stops recording.

Wired vs wireless security cameras: which is more reliable?

Wired cameras are the most reliable choice for steady, round the clock recording. They do not depend on WiFi, a power point near the camera, or a battery that needs charging. Reliable recording also depends on the recorder and its storage. We explain storage in how much storage your NVR really needs.

Why we recommend wired cameras

Security cameras only help if they are recording when something happens. That is why, for your home's main security, we recommend and install wired cameras. They record continuously, they keep working when the WiFi is slow, and there are no batteries to forget.

Wireless and battery cameras have their place as a quick, temporary fix. But we do not recommend relying on them to protect your home. The bigger job is making sure each wired camera can see the right spot, which is why camera placement matters more than package size.

Common questions

Do wireless security cameras need power?

Yes. A WiFi camera still needs power from a power point or a cable. Only battery cameras run without a power cable, and they stop recording when the battery runs flat.

Can wired cameras work without the internet?

Yes. Wired cameras record to a recorder at your home without internet. You only need internet to view the cameras on your phone while you are away.
